I am trying to run a programme which is using PGPLOT.When I call it from browser I get following error message. -------- %PGPLOT, Unable to read font file: grfont.dat %PGPLOT, Use environment variable PGPLOT_FONT to specify the location of the PGPLOT grfont.dat file. %PGPLOT, PGENV: no graphics device has been selected %PGPLOT, PGBBUF: no graphics device has been selected %PGPLOT, PGMTXT: no graphics device has been selected %PGPLOT, PGMTXT: no graphics device has been selected %PGPLOT, PGMTXT: no graphics device has been selected %PGPLOT, PGEBUF: no graphics device has been selected ---------- grfont.dat file is on on my system under c:\XAMPP\perl\lib and I have set it as enviorment variable PGPLOT_FONT. Any help will be much appreciated. Thanks,

thanks for your response. I added $ENV{PGPLOT_FONT} ||= 'c:\XAMPP\perl\lib\grfont.dat'; But I still get same response.
